Using the graphing you graph the two equations and then find the point where the two lines of the equation meet.
Hope this helps :)
Hello there!
If x = -3
Calculate x^2 - x
We need to replace x by 3
3^2 - 3
=3 * 3 - 3
= 9 - 3
= 6
I hope this helps!
A 80 square meter I’m not quite sure
A. The Area of one triangular face would be 320 ft². B. The total surface area, in square feet, of the square pyramid is 2,304 ft².
<h3>What is the area of the triangle?</h3>
The Area of one triangular face can be calculated as;
A = area of triangle = ½ x b x h
Where,
b = 32 ft
h = 20 ft
A = ½ x 32 x 20 = 16 x 20
A = 320 ft²
Area of 1 triangular face = 320 ft²
B.
Total surface area = area of the 4 triangular faces + area of the base of the square pyramid
T.S.A = 4(320) + (s²)
Where,
s = 32 ft
T.S.A = 4(320) + (32²)
T.S.A = 1,280 + 1,024
= 2,304 ft²
